F - False.
The nucleus of an atom is positively charge.
Answer:
v = - 0.4 m/s
Explanation:
Initial momentum is zero as neither gun nor bullet have velocity
Conservation of momentum
0 = 0.020(50) + 2.5v
v = - 0.4 m/s
Impulse is change in momentum. The initial momentum was
0.1kg*11m/s=1.1kg m/s.
The second momentum is 0.1*(-8.8m/s)=-0.88 (since it's moving backward now)
The difference is P1-P2 = 1.1-(-0.88)=1.98kg m/s
Answer:
Explanation:
It doesn't mean it equal to each other. lets say x is directly proportional to y. Here, if something happens to x then, y will do the same thing. for example, if x increases, then y also increases. similarly, if x decreases, then y also decreases. therefore, x is something or lets say it is a major factor that decides the fate of y.
